Emotion, Depression, and Asymmetric Brain Function
… with abnormal functional asymmetries in frontal cortex, functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET) studies have largely failed to identify specific brain regions showing this effect. This failure likely stems in part from the widespread use of …

Electrocorticographic Neural Correlates of Arm Movements and Associated Goal Orientation in Humans
… direction, position and speed throughout the cortex. In particular, velocity tuning was best represented spectrally in a high gamma band from around 90-150 Hz in the primary motor cortical regions. In dorsolateral prefrontal cortex: DLPFC), cortical activity in the 150-250 Hz band of the ECoG …

Exploration of the influence of emotionally primed environments on creativity and related patterns of brain activity
… analysis suggested that the brain regions of the dorsolateral prefrontal cortex (DLPFC), anterior cingulate gyrus (ACC), and anterior insula are active under both stimuli associated with increased divergent thinking. Future work is needed to investigate specifically how these brain regions may …

PTSD Symptom Severity and Neurocognitive Performance as a Function of Combined TMS and Imaginal Exposure in OIF/OEF Combat Veterans with Treatment Resistant PTSD
… magnetic stimulation (TMS) to the right dorsolateral prefrontal cortex (DLPFC) and the supplementary motor area (SMA) with a standardized exposure protocol for the treatment of chronic, treatment-resistant PTSD. The aims are to (1) determine if the treatment is safe and well tolerated, …

Transcranial Direct Current Stimulation of the Dorsolateral Prefrontal Cortex Does Not Improve Handgrip Time-to-Failure or Alter Central or Peripheral Hemodynamics
… study was to determine if tDCS delivered to the dorsolateral prefrontal cortex (DLPFC) would improve handgrip time-to-failure in adults 60 years old and older. Twenty-five participants completed five maximal voluntary contractions, followed by 20-minutes of a-tDCS or SHAM conditions. Next, …

PERSISTENT ACTIVITY DURING WORKING MEMORY: MATURATION AND CORTICAL SPECIALIZATION
… one of the most critical cognitive functions and dorsolateral prefrontal cortex (dlPFC) has generally been recognized as the seat of working memory. Development of working memory ability through adolescence, accompanied by structural changes has been reported in human studies, however, how …

Cognitive Control as a Function of Anger Expression Style: A Combined ERP and fMRI Investigation
… that anger-out was associated with greater left dorsolateral prefrontal cortex (DLPFC) activity than anger-in, evidence in support of the motivational model of emotion. Contrary to hypotheses, anger-out was not linked to cognitive control impairment. However, consistent with hypotheses, anger-in …

The involvement of the primate frontal cortex-basal ganglia system in arbitrary visuomotor association learning
… the goal of this thesis to examine the frontal cortex-basal ganglia system during arbitrary visuomotor association learning, the forming of arbitrary links between visual stimuli and motor responses (e.g. red means stop), a fundamental learning process that underlies much of our complex behavior …

Risky Decision-Making Under Social Influence
… about risky decisions follow others and proposes dorsolateral prefrontal cortex (dlPFC) as a 'controller' of this heuristic. Study 2 finds that giving individuals agency in viewing social information increases the utility of that information. Study 3 finds that some individuals can modulate brain …

Neural and Behavioral Evidence for a Link Between Mobile Technology Usage and Intertemporal Preference
… the ventral striatum (vSTR) to the ventromedial prefrontal cortex (vmPFC) and dorsolateral prefrontal cortex (dlPFC), pathways that have been previously implicated as biological markers for individual differences in intertemporal preference. Regression analyses revealed that both pathways …

Substrates of social functioning in individuals with VCFS
… larger amygdala and insula volumes and smaller prefrontal cortex (PFC), orbitofrontal cortex (OFC), dorsolateral prefrontal cortex (DLPFC), insula, superior temorpal sulcus (STS), and anterior cingulate cortex (ACC) volumes relative to controls. In addition, scores on the Child Behavior …

The Effects of tDCS on the Identification of Emotion in a Speaker’s Voice in Young Adults with Autism
… study examined whether applying tDCS to the dorsolateral prefrontal cortex (DLPFC), when paired with social communication intervention, enhanced auditory emotion recognition in this population. Mixed-model ANOVAs revealed significant improvements over time for Affect, Social Perception (SP), …

Wandering minds, restless brains and mindful thinking : a network-based perspective
… in relation to connectivity between the medial prefrontal cortex (MPFC) and dorsolateral prefrontal cortex (DLPFC). The DLPFC is a major component of the executive control network that increased in activation during tasks involving working memory and mental control. Young adults exhibit greater …

The Role of the DLPFC in Bilingual and Monolingual Switching: Evidence from MVPA and tDCS
… brain involved in both types of control). The dorsolateral prefrontal cortex (DLPFC) is one candidate brain region involved in these two types of control. The current studies had two aims. The first was to determine whether bilingual language control and non-linguistic control relate similarly …

The Effects of Multiple-Intervention Neurofeedback on Engineering Design Ideation
… feedback sessions, particularly in the right dorsolateral prefrontal cortex (DLPFC), which is associated with generating new ideas. Multiple neurofeedback sessions showed performance improvements in engineering design tasks, with changes in task-related oxygenation in the prefrontal cortex. …

BRAIN MECHANISMS SUPPORTING EXPECTATION AND TOP-DOWN ATTENTION TO PAINFUL STIMULI
… of the cue. Superior parietal lobule/precuneus, dorsolateral prefrontal cortex (DLPFC) and cerebellum were implicated in these processes. In addition, attention to spatial and intensity features of pain activated intraparietal sulcus and frontal eye fields. These areas likely activated brain …

Orbitofrontal Cortex Repetitive Transcranial Magnetic Stimulation for the Treatment of Major Depressive Disorder
… (MDD). Conventional rTMS in MDD targets the dorsolateral prefrontal cortex (DLPFC) or the dorsomedial prefrontal cortex (DMPFC). However, many patients do not respond to DLPFC-rTMS or DMPFC-rTMS. Recent evidence suggests that the right lateral orbitofrontal cortex (OFC) plays a key role in …

Effects of Music on the Pain Response in the Central Nervous System Using Functional Magnetic Resonance Imaging
… These regions include the spinothalamic tract, dorsolateral prefrontal cortex (DLPFC), periaqueductal grey (PAG), rostral ventromedial medulla (RVM), and the dorsal gray matter of the spinal cord. The data suggest that music seems to engage mesolimbic and mesocortical brain regions to activate …

Neural Activity Within and Between Visual and Executive Areas Is Modulated Post-Locomotion in Rhesus Macaques
… V4, a mid-tier visual cortical region, and the dorsolateral prefrontal cortex (dlPFC), a higher order executive area, while a rhesus macaque engaged in a visually guided behavioral choice task following a period of sustained physical activity. Further, we investigated how population and …

Neural basis of private and social decision-making: new insights from transcranial ultrasound stimulation and multivariate analysis
… (TUS). We found that the rostromedial prefrontal cortex (rmPFC) is involved in the integration of decision variables and that the precuneus/posterior cingulate cortex (PCC) is involved in the anticipation of regret, but not in its experience. We also found that social comparison is …
